Replacing final smash?

[frozenfire]

 This is probably a noob question but I have mario and luigi over ice climbers pack but I want them to use the classic sonic and tails final smash( tornado thing) while they still have the mario and luigi moveset. How would I go about doing this?

To replace/edit a FS you need the Fit****Final.pac, in your case FitPopoFinal.pac Replace each brres file with the corresponding brres file. Then in PSA replace all of the Final Smash data with the final smash data from the final smash you want. For the animation replace the chr0 final smash animation file with the new final smash chr0 file. I can link you to a few video tutorials if you want.
